1.     Project Components

1.1     MARTINI

MARTINI is basically a Durham Physics group R & D project. However it offers a valuable opportunity to test an adaptive optics system on the WHT. In carrying out scientific observations allocated by PATT, it will also provide information about the GHRIL environment (seeing, thermal and electromagnetic) which will be highly relevant to NAOMI from the both the Adaptive Optics and Infrared performance aspects. The NAOMI project has supplemented the MARTINI project funds to a small degree in order that as much as possible can be learned from MARTINI. NAOMI has no formal management control over MARTINI but the MARTINI manager (Pete Doel) is being very co-operative in following suggestions from the NAOMI project concerning performing laboratory tests and timing of experiments so that they do not interfere with ELECTRA and NAOMI development.

 

The timetable is:

·      July 1996:  full laboratory test of MARTINI

·      Aug 1996:  PATT observing, including pre-observing commissioning

·      1996 Semester B onwards: available for PATT observing (level of support still and issue needing to be resolved).

1.2     ELECTRA

The original Durham University long-term goal for ELECTRA is optically co-phased tip-tilt and piston AO correction, via tip-tilt with no co-phasing (E0) and then co-phased sub-areas. The co-phased sub-areas stage has now been replaced by E1, an IR co-phased step. E1 provides a crucial test of the DM which will be used for NAOMI and a WFS which has almost identical basic operation and probably the same CCD that will be used for NAOMI. ELECTRA has its own opto-mechanical chassis.

 

The timetable is:

·      Dec 96 - May 97:  E0  full laboratory test

·      Jun 1997:  E0 commissioning run

·      May - Oct 1997: E1 laboratory development & test

·      End Nov 1997:  Earliest date E1 available for commissioning run

1.3     NAOMI

NAOMI is to be the facility instrument, utilising the ELECTRA DM but with an independent opto-mechanical chassis and a Real Time Control System developed from ELECTRA.

 

The NAOMI timetable is:

·      Full laboratory integration:  Oct 98 - Feb 99

·      Commissioning:  Mar 1999

1.4     JOSE

Site evaluation to measure key atmospheric properties is taking place on the WHT via an over-ride programme and campaign measurements. Results will be used to assist RTCS optimization and development of observing procedures and visualization.

 

The JOSE timetable on the WHT is:

·      Start of over-rides:  December 1995

·      Observations and campaign continue to ~ mid-1997.

2.    On terms currently set by PPARC, once allocations are made the Observatories it is formally the responsibility of the respective Directors to deliver the agreed product. The Project Manager does not have any direct authority over Observatory staff unless through existing internal line management.

 

3.    The Project Scientist and Systems Engineer grant has been let until March 1998.

 

4.    The goal for the Durham The RTCS and Visualization Development grant is to let it shortly after an agreement is confirmed between the Director, ING and Durham University on the relationship between the ELECTRA and NAOMI projects and the mutual development and sharing of key components. The grant is likely to be for the full planned period of the NAOMI project, to approximately Mar 1999.

4.     Project Reporting

4.1     Project Manager Reporting to Budget Holder

The Project Manager will report formally to the Budget Holder monthly on the status of the project at each month’s end, by the end of the following month, giving total project expenditure, staff resources used, milestones achieved, a general progress summary and a note of any changes in total projected cost . Out-turn estimates will be provided at appropriate times. The Budget Holder will be notified of any intended changes of project scientific goals before they are formally agreed with the Project Scientist and External Project Scientist.

4.2     Local Managers Reporting to Project Manager

The Local Managers will report formally to the Project Manager monthly, on the status of the project at each month’s end, by the middle of the following month, giving total project expenditure, staff resources used, milestones achieved, a general progress summary and a note of any changes in total projected cost . Local Managers will provide Out-turn estimates in a timely way. They will also keep in more frequent contact with the Project Manager through informal reports by Email, especially concerning any problems, significant progress or changes in staff effort availability. A more detailed description of the Local Managers’ responsibilities is given in the Work Package Cover Document. A template form for the monthly formal report has been given to the Local Managers.

5.     Project Documentation

Figure 1 shows a flow chart indicating the key NAOMI documents. All key documents are held in the BSCW Document Handling Facility under version control.

 

The defining document for what the system must do when it is delivered to La Palma is the Top Level Scientific and Operational Requirements document.

 

Procurement of a system to meet these requirements is carried out via  a series of Work Packages which define the work and product required from each of the sites.

 

The WPs are linked to the TLSOR document via a Technical Description document which contains some details of implementation. This link document gives the main overall description of how the TLSOR will be met in practice and includes  explanatory text to assist in a global understanding of NAOMI. It has links down from the TLSOR document and links up from the WP descriptions.

 

Associated with the WPs is a WP Cover document which describes how the Project expects the WPs to be managed and reported on and other WP guidelines.

 

Each WP has an associated Access database which lists all the individual requirements for that WP. Thus there is a WFS Requirements database, an OMC Requirements database and a Software User Requirements databse. These are set up so that they can be used as a Requirements Traceability Matrix.

 

The chart also shows how the Software Prototypes feed into the development of the system and where WP and System Reviews lie in the NAOMI Management process.

6.     Project Implementation - Responsibilities

6.1     RGO Work

RGO are responsible for the following.

a)    The design and production of the WFS, its pick-off mechanism and its non-common-path calibration. Likewise for a tip-tilt sensor if this is implemented (it is not in the baseline plan).

e)    Provision of at least two personnel with a good and appropriate knowledge of the RGO work to take part in the system integration at a site specified by the Project Manager with adequate backup remotely if necessary to assist in solving any problems related specifically to the RGO work.

f)     Provision of the External Project Scientist

 

6.2     ROE Work

ROE are responsible for the following.

a)    The overall optical and mechanical layout, including the definition of space envelopes, cabling routes, location of electronics racks.

b)   Design  and production of all opto-mechanical components on the optical bench except the DM, the WFS and its pick-off and its non-common-path calibration unit.

c)    Design and production of system handling equipment, packaging and storage equipment.

d)   Engineering level control of all mechanisms covered by the previous statement.

e)    Provision of at least two people with a good and appropriate knowledge of the ROE work to take part in the system integration at a site specified by the Project Manager with adequate backup remotely if necessary to assist in solving any problems related specifically to the ROE work.

f)     Provision of people on the same terms as above to participate in system commissioning at the WHT.

g)    Provision of the Project Manager.

 

6.3     Durham Work

Durham University Physics Department are responsible for the following work. Because of the close connection between the ELECTRA and NAOMI projects a special agreement between the ING and Durham is under discussion which covers these responsibilities and their funding in more detail. Once completed, that agreement will supersede the description of Durham responsibilities given here, except for the Project Scientist and Systems Engineer.

a)    All E0 development and components (these are not managed or funded by the NAOMI project).

b)   RTCS and Visualization software and hardware for E1 (these are not funded by the NAOMI project).

c)    All opto-mechanical components of E1 (these are not funded by the NAOMI project).

d)   Laboratory integration of E1 (this is not funded by the NAOMI project except where it involves effort from RGO or ROE).

e)    Commissioning of E1 (funded by the NAOMI project)

f)     RTCS and Visualization software and hardware for NAOMI.

g)    Provision of at least two people with a good and appropriate knowledge of the Durham work to take part in the system integration at a site specified by the Project Manager with adequate backup remotely if necessary to assist in solving any problems related specifically to the Durham work.

h)    Provision of people on the same terms as above to participate in system commissioning at the WHT.

i)      Provision of the Project Scientist and the Project Systems Engineer

j)     Current expectation is that Durham also supply the laboratory for the final integration and system pre-delivery acceptance testing.

 

6.4     ING Work

The ING on La Palma are responsible for the following work.

a)    Advising the Project on any local standards required for software, computing, electronics and electrical hardware, safety requirements, handling requirements, environment and space envelope constraints.

b)   Provision of removal equipment for taking off and re-installing NAOMI as will be agreed in the handling requirements, storage space, a set-up and test location for NAOMI when not on GHRIL.

c)    Provision of electrical power and any coolants agreed with them to be needed for NAOMI system operation

d)   Provision of a GHRIL  environment which, without the NAOMI system present  does not further degrade telescope seeing compared to that measured at prime or Cassegrain focus

e)    Provision of a global heat removal capability servicing GHRIL to which NAOMI systems may be easily attached.

f)     Provision of an adequate EM-environment (good earthing facility, em screening).

g)    Provision of two people to attend a significant portion of the system integration and acceptance testing, to be trained in the use of the system and to agree the passing of the acceptance tests.

h)    Note that the NAOMI project expects all the above, with the exception of a) and possibly b) and g) , to be funded from ING operations.

 

6.5     System Integration

The location for full system integration will be determined based on the project needs and facilities available at the required time. The current expectation is that the system integration will take place in Durham. However intermediate integration stages will take place at the most suitable location (decided by the Project Manager) for the work in question.

 

The responsibility for the integration will be carried ultimately by the Project Manager, assisted by the Project Scientist and Systems Engineer. However there is a joint responsibility for the Work Package providers to supply effort appropriate for the integration (see relevant bullets above).   

6.6     Acceptance Testing

The location for the acceptance testing will be the same as for the system integration. It will occur in approximately the last two weeks of the integration period.

 

The responsibility for the acceptance will be with the ING. It is envisaged that one of the ING astronomers or engineers attending the integration and acceptance testing phases will make a recommendation to the Director, ING, who will then formally accept the full system as having passed the laboratory tests. The actual tests to be carried out should be agreed between the External Project Scientist, the Project Scientist, the Project Manager, the Systems Engineer and the Director, ING or his nominee, prior to the start of the laboratory integration phase.

6.7     System Commissioning

The location for commissioning will be the WHT. It is likely there will be a pre-GHRIL assembly and testing of the system after its delivery to the island, then a final commissioning at GHRIL.

 

Responsibility for system commissioning will be as for system integration.

 

7.     Project Implementation - Stages

7.1     Introduction

A milestone chart generated from the Local Managers’ Project Plans and an integrated top-level plan will be maintained by the Project Manager. The current version of the milestone chart  is attached. The following sections define some review and other major stages to implementation. They do not replace or substitute for the project plan Gantt chart. For the definition of PDR, CDR and System Engineering Reviews to be used by the NAOMI project see the document AOW/MAN/AJL/8.0/07/96.

7.2     Preliminary Design Reviews (PDR)

The Opto-mechanical Chassis (o-m-c) work package and the Wavefront Sensor  (WFS) work package will have their own independent PDRs. Material for these will be supplied in a single written document two weeks before the date of the review.

7.3     Critical Design Reviews (CDR)

The Opto-mechanical Chassis work package and the Wavefront Sensor work package will have their own independent CDRs. Material for these will be supplied in a single written document two weeks before the date of the review.

 

7.4     System Review (1)

There will not be a full system PDR. However a system review will be held after the o-m-c and WFS PDRs, the supervisory software architecture design is complete and possibly after E0 has been evaluated following its observing (provided its commissioning run takes place in a timely way). It will cover all aspects of the project (including RTCS and Supervisory System software and hardware) as they are at the time of the review.  However the review will concentrate on checking that the proposed designs meet overall functionality  requirements and on system interfaces. The review will be conducted by the Project Scientist, Project Manager and a La Palma representative, possibly with one invited senior reviewer, and will consist of presentations by the local managers and/or appropriate engineers, summarising the designs, plans and status of each project area and giving detail specifically in interface areas and in functionality. It will also include the draft plan for system integration. Its goal will be to ensure that design and planned implementation details remain compatible between work packages and to ensure that the proposed full system meets the agreed scientific and operational requirements.

7.5     System Review (2)

There will not be a full system CDR. However a second system review will be held after the o-m-c and WFS CDRs, a prototype supervisory system has been built and E1 lab testing is completed. The review will be conducted by the Project Scientist, Project Manager and a La Palma representative and will consist of presentations by the local managers and/or appropriate engineers. One goal will be to ensure that design and planned implementation details remain compatible between work packages and to ensure that the proposed full system meets the agreed scientific and operational requirements. An additional goal will be to confirm the various integration stages over which components will be tested with all or parts of the rest of the system.

7.6     System Integration

There will be one main phase of full system integration but there may be several earlier preliminary integration phases where key sub-components are tested together. These phases will be defined by the time of the second system engineering review and agreed at or shortly after the review. Some possible preliminary integration phases are listed in section 7.10. The full system integration stage is expected to take approximately 18 weeks.

7.7     Acceptance Testing

Acceptance tests and pass criteria will be defined before the full system integration phase begins. They should be such as to demonstrate in the laboratory, in a of period less than two weeks, that the system is likely to meet its scientific and operational requirements at the telescope.

7.8     Commissioning

It is currently envisaged that on arrival at La Palma the NAOMI system will be installed and tested on its off-GHRIL bench, to confirm no damage was caused during shipping. Tests will be key sub-elements of the acceptance tests. NAOMI will then be moved to GHRIL for full telescope commissioning. Two runs of not less than 7 nights, separated by about a week, are anticipated. Each run should be preceded by about 4 days at GHRIL using day-time only for set-up and environment tests.

7.9     Formal Acceptance of the NAOMI System

Formal acceptance of the NAOMI system as a delivered instrument, by the Director  ING, would be expected to follow the second commissioning run.

7.10     Alternative Strategies

7.10.1     Introduction

Most components of the NAOMI system are relatively low risk and/or can be bought to a well defined specification so do not require early consideration of alternative procurement strategies.  The most challenging components are the Deformable Mirror and the RTCS system. Therefore alternative strategies to the main route for their supply have been considered and are described briefly below.

7.10.2     RTCS and Visualization

Section 6.3 describes the work intended for Durham, which will be authorized via a grant to develop the NAOMI RTCS, Visualization and GUI.  After the E0 and E1 commissioning stages, an internal evaluation will be held which could include a cost-benefit analysis of the route to complete the NAOMI RTCS and Visualization requirements. As NAOMI plans have developed, they have involved an increasing level of re-use of ELECTRA products so it is now unlikely that a significant amount of software will be bought from an external source. Decision points between continuing with E1 software development into NAOMI and any logical architecture changes and user requirement revisions will be set up by use of  a series of software prototypes. Should serious problems occur with the ELECTRA system, other potential software suppliers have been identified from whom software could be purchased.

 

Figure 2 is a flow chart illustrating the relationship between the time line of the E0 - E1 - NAOMI  RTCS prototype stages. The interaction with the core supervisory system and the WFS most need to be considered carefully.

7.10.3     Deformable Mirror

The main strategy is to develop the ELECTRA mirror to be the NAOMI system DM, for reasons described in the NAOMI Technical Descriptions document. A second DM, suitable as a substitute for the ELECTRA DM, would be purchased and characterised by Durham as a laboratory system to be made immediately available for NAOMI should the main DM fail. There are several stages at which it could be decided to use the backup DM as the main DM. The approach to provision and use of the continuous face-sheet DM is described in the Memorandum of Understanding between Durham and the ING.  Given a lead time in the purchase and implementation of the alternative DM (about 9 months combined) there is clearly a latest date by which it could be purchased and not significantly delay the final implementation of NAOMI. This date is included in the milestone table and the plan would be to make any decision before that date.  Figure 3 shows schematically the concept of how DM procurement will be handled. However the continuous face-sheet DM purchase need not necessarily wait until E-1 as it is already recognised that Durham will need an alternative to the segmented DM to continue meeting rolling grant goals.

9.     Figure Captions

Figure 1: Project Documentation chart (see text for explanation).

Figure 2 :  A flow chart indicating the potential development route for the E0 -E1 - NAOMI RTCS software. The diagram is based on the idea that the goal with each prototype is as much as possible to check requirements driven by the user, with a second goal of testing some key system functionality. Therefore the User Requirements Document and its development is folded top and bottom of the figure and decisions, design changes etc are related back to and driven by User Requirements.

Figure 3 :  A flow chart indicating the key stages in the development of the ELECTRA Deformable Mirror. The key points are indicated at which a parallel purchase and characterization of an alternative mirror interact with the main DM development route. The alternative mirror could be used either as a backup or selected as a strategic switch to being the main mirror.
